Valacyclovir — Glossary Definition
Valacyclovir is an antiviral medication used for conditions including cold sores and genital herpes. Valtrex® is the brand name for valacyclovir.
What is valacyclovir used for?
Valacyclovir can be used for oral herpes, genital herpes outbreaks, and daily suppressive therapy in appropriate patients. It is not a cure for herpes.
Is valacyclovir the same as Valtrex®?
Valtrex is the brand name. Valacyclovir is the generic active ingredient. Bidwell uses the terms carefully so patients understand the medication without implying that Bidwell sells the brand.
What does Bidwell treat?
Bidwell treats adults ages 18-64 with a prior herpes diagnosis. Bidwell does not diagnose herpes online.
What it does (and does not do)
- Helps treat outbreaks and can be used for daily suppressive therapy in appropriate patients.
- Does not cure herpes; the virus remains in the body.
- Does not replace diagnosis — first possible outbreaks should be confirmed with testing.
Why timing matters
Outbreak treatment is generally most effective when started early. If you’re unsure whether symptoms are herpes or something else, diagnosis comes first.
Safety screening (high level)
- Kidney disease can change dosing and risk.
- Drug interactions and pregnancy considerations matter.
- Eye symptoms (pain, light sensitivity, vision changes) are urgent.

Outbreak vs suppressive therapy
- Outbreak treatment: short-course treatment used when symptoms start.
- Suppressive therapy: daily medication used to reduce outbreak frequency and transmission risk in appropriate patients.
Frequently asked questions
Can I spread herpes without symptoms?
Yes. Asymptomatic shedding can occur. Suppressive therapy and risk-reduction strategies can help, but no approach eliminates risk completely.

Clinical context
This term is used on Bidwell pages to support clear, consistent language across guides and treatment pages. The goal is understanding and safe next steps, not self-diagnosis.
When to seek in-person care
- Severe symptoms or rapidly worsening symptoms
- Pregnancy or possible pregnancy
- Unclear diagnosis or treatment failure
How Bidwell uses this definition
Bidwell’s public pages are written so patients can understand what a clinician means, and so the same term is used consistently across related treatment pages, clinical notes, and guides. This is intentionally not a full textbook chapter — it’s a practical definition with safety boundaries.
If you are reading this because you are trying to self-diagnose, a good rule is: if you are uncertain what the diagnosis is, or you have red flags (severe pain, fever, pregnancy, eye involvement, rapid worsening), in-person evaluation and testing is often the safest next step.
Questions that help a clinician
- When did symptoms start and how have they changed day-by-day?
- What have you already tried, and did anything partially help?
- Any prior diagnosis of the same condition?
- Any pregnancy possibility or immune suppression?
- Any new medications, allergies, or recent antibiotic use?
Practical note
If your situation is atypical or worsening, an exam and testing can prevent unnecessary or incorrect treatment cycles.
